Abstract

The architectural concept of a safety-related programmable electronic system featuring task-oriented real-time execution is presented. Its most essential characteristics are task execution without the use of asynchronous interrupts, scheduling in direct reference to Universal Time Co-ordinated, and an integrative hardware approach to detection and processing of failures, forward recovery and non-intrusive monitoring. The architecture is based on physical separation of task execution and task administration, which is realised in form of a digital logic circuit. Time is quantised into Execution Intervals, and tasks are partitioned into Execution Blocks matching these intervals. This concept lowers the complexity of both hardware architecture and temporal behaviour and, thus, conforms particularly well with the safety standard IEC 61508.
